8 Claims. (Cl. 229-53) My invention relates to bags, and has special Figure 1 is a plan view of a blank from which reference to linings of crinkled paper for burlap, my improved lining may be formed; or other textile fabric bags. My invention Fig. 2 is a side elevation, partly broken away, further relates to a method of making such of my improved lining at'the completion of the articles. sewing of the seams; 60

In forming the lining for bags of the character Fig. 3 is a view in perspective of the completed indicated, it has been customary to fold a sheet lining, ready to be inserted in the bag; of crinkled paper. upon itself in the direction Fig. 4 is a side view of a portion of a bag with of the crinkles and secure the longitudinal edges my improved lining inserted therein;-

When the bag has been filled it may be would be impracticable to sew in the upper end easily closed by bringing the edges of the open of the lining with the upper end of the bag as ends of the lining and the outer envelope tothe unstretchability of the paper longitudinally gether, and securing them by a line of stitches of the lining would result in the stitches easily 12 as shown in Fig. 7 which may be done by 100 tearing hand or by suitable sewing mechanism.

One of the objects of the present invention is With the lining constructed as above deto provide a paper-lined bag which overcomes scribed, during the filling of the bag, the folds the disadvantages above described of prior con= at the longitudinal edge portions provide the structio snecessary slack transversely thereof, and the 105 Another of the objects of the present inventransversely extending crinkles provide the tion is to provide a novel and improved bag of necessary stretchability longitudinally of the linthe character indicated and method of forming ing, allowing the lining to freely stretch to the samefull capacity of thebag without danger of breake e to the d w ing the paper. Also, during the filling of the bag 110 the unseamed bottom of the lining is free to stretch and adjust itself tothe bottom of the fabric envelope. The longitudinal stretchability of the crinkled paper allows the upper end of the lining to be sewed in with the upper end of the fabric envelope without danger of the stitches pulling out so that it is unnecessary to tuck in the upper end of the lining previously to sewing the upper end of the bag. Such closing .of the upper end of the bag may be performed by the usual automatic sewing mechanism employed with present day bag filling machines. Also, by sewing in the upper end of the lining with the fabric, there is an appreciable saving of paper over the prior constructions which have a projecting end to be tucked in as above described. During the handling of the filled bag, the paper readily stretches longitudinally thereof, the unseamed bottom of the lining is permitted to freely expand and fit against the bottom of the burlap envelope, and the folds or tucks at the longitudinal edge portions of the lining provide plenty of slack to prevent any undue strain transversely of the lining, so that danger of breakage of the lining is reduced to a minimum. The longitudinally extending sewed seams hold the lining from be coming unduly distorted and serve to reinforce the lining longitudinally thereof.

Instead of providing folds adjacent the longitudinal sewed seams as above described, it may be desirable in some instances to provide longitudinally extending folds 14 midway of said sewed seams '(Fig. 8). Preferably these folds are of dove-tail form as shown. Also, the paper may becrinkled longitudinally of the lining as well as transversely so as to provide the necessary slack, or the desired result may be otherwise secured.

As will be evident to those skilled in the art, my invention permits various modifications without departing from the spirit thereof or the scope of the appended claims.

What I claim is:

1. A lining for insertion in a fabric bag of the class described made from a sheet of crinkled paper with the crinkles extending transversely thereof to provide for longitudinal stretchability and with the sheet folded over upon itself on a transverse line, and seams securing the longitudinal edges together, said lining having longitudinally extending means to provide for circumferential stretchability.

2. A bag lining of the class described made from a sheet of crinkled paper, with the crinkles extending transversely thereof and with the sheet folded over upon itself on a transverse line, the longitudinal edges of the folded sheet I being turned over, and lines of stitching securing from a sheet of crinkled paper, with the crinkles extending transversely thereof and with the sheet folded over upon itself on a transverse line, and seams securing the adjacent longitudinal edges of the folded, sheet together, the

seamed edges of the bag being tucked inwardly to provide for circumferential stretchability.

5. A lining, for insertion in a fabric bag, made of crinkled paper with the crinkles extending transversely thereof to provide for longitudinal stretchability, and reinforcing means extending lengthwise of the bag'on diametrically opposed lines, said lining having longitudinally extending means to provide for circumferential stretchability.

6. A lining, adapted for insertion in a fabric bag of the class described, made from a sheet of crinkled paper with the crinkles extending transversely thereof to provide for longitudinal stretchability and with the sheet folded over upon itself on a transverse line, and seams securing the longitudinal edges together, the sides of the bag thus formed having longitudinally extending folds positioned midway between the sewed seams to provide for circumferential stretchability.

7. A bag lining of the class described made from a sheet of crinkled paper with the crinkles extending transversely thereof and with the sheet folded over upon itself on a transverse line, and seams securing the longitudinal edges together, the bag thus formed having folded over portions extending longitudinally thereof to provide slack in opening up the bag.

8. A paper lining for a fabric bag of the class described, said lining being transversely crinkled so as to provide for longitudinal stretchability thereof and having longitudinally extending means to provide for circumferential stretchability, said lining being in the form of a bag having a closed lower end and sides adapted to beinserted ins the fabric bag with the bottom of the lining adjacent the bottom thereof, and said provisions for longitudinal and circumferential stretchability being such that when the lined bag is filled with finely divided material and the" bag is closed the lining may freely adjust itself to the inner surface of the bag during handling without undue strain being placed thereon.
